Mirror Crack'd from Side to Side

Till now I'd only read Christie in the form of Poirot stories in an enclosed setting: Murder on the Orient Express where the train is snowed in; Death on the Nile where everyone is stuck on a boat. This one is set in Miss Marple's town of St. Mary Mead, so people could, and do, come and go. I was actually surprised at how little screen time Miss Marple herself actually gets. The biggest part probably goes to Marple's nephew, Chief Inspector Craddock.

The big spoiler for this story is that the victim signs her own death warrant by admitting that she transmitted a German measles infection to a pregnant woman, resulting in the child having permanent physical and intellectual problems, and the mother having lifelong PTSD from that.

Fortunately Rubella is a thing of the past and people don't go around spreading disease because they're afraid of missing out on an opportunity to socialize.

The story snowballs alarmingly as further characters are killed off because they Knew Too Much, right up to the last chapter when there is another unexpected death, and we are left wondering if that one was suicide or also murder, or if the distinction even matters after everything that happened.

This book might have benefited from a bit of a trim at the start and a bit of fluffing up in the middle as the events happened which led to the additional consequential murders. But it was altogether a pretty painless read and the (rushed) conclusion satisfying.
